4 Phase Plot Prestgard, Trygve 2019-12-28 00:00 UTC
3 Light curve zoom: Possible Eclipse in ASAS-SN Prestgard, Trygve 2018-10-29 22:55 UTC Possible strong (V >1.5 mag) fading with symetrical recovery in ASAS-SN, very much the morphology of an eclipse (minimum at HJD 2457610). Another [weaker] fading event at ~ HJD 2458100, and yet another starting at ~ HJD 2458300.
2 Corrected Light Curve: IRAS 13079-6622 Prestgard, Trygve 2018-10-29 00:21 UTC Based on corrected ASAS-3, APASS and ASAS-SN Visual Magnitude data.
1 Bipolar lobes Prestgard, Trygve 2018-10-29 00:21 UTC The lobes are best visible in optical red filters, with apparent emissions in Halpha.
